To allwiwmit may concern:

Be it known that 1, JOHN P. GRIFFIN, a

. subject of the King of Great Britain, residing at Pearce, Province ofAlberta, and Dominion of Canada, haveinvented certain. new and usefulImprovements in Door- Checks; and I do hereby declare the followingto bea full, clear, and exact description of the invention, such as wlllenable others skilled in the art to which it appertains to make and usethe same.

This mventlon relates to door checks and has particular reference to afoot operated not accidentallyjar looseandwhicli will .yield should thedoor become. violently pushed floor.

lVith these'and other objects in view as without liability of injury ,tothe will appear as the description proceeds, the

invention comprises the various novel tea tures of construction,combination and ar-' rangements of partsas will belfully describedhereinafter andafterward specifically claimed.

Referring tothe drawings, Figure 1 represents a perspective view of thedoor check attached to. the lower part of the door.

7 taken on a plane indicated by the line 1- 1 on Fig. 1, and

Fig. 5 represents a sectional elevation of the lower end of the plungerrod and tip.

I11 order that the construction and opera-f tion of the invention may bereadily comprehended by those skilled in the art to which the inventionrelates, I have illustrated an improved embodiment thereof in theaccompanying drawings, and will now proceed to fully describe the same,in connection with said drawings in which 1 is the casing of the doorcheck and 2 the cover plate l therefor, which latter is providedSpecification of Letters Patent.

with laterally extending ribs 3 to fit within the casing and holdthecover plate against casual displacement with respect to the cas ing.The device is adapted to be attached to the bottom part of a door byscrews or other fastening elements 1 which extend through the casingand. cover plate.

A spring 5, which may be of leaf spring or spring wire construction, ispositioned horizontally w thin the casmg and has one end rlgidly butremovably connected to the casing as indicated at 6. The casing 1carries a supporting lug 7 which projects laterally beneath the springadjacent its anchored end.

The free end of the spring is pivotally connected as at 8 to the plungerrod 9 mounted forv vertical sliding movement through the bottom of thecasing as at 10.

This plunger rod has detachably connected to its lower end a floorengaging tip .which comprises a metallic socket l1 threadedly connectedto the plunger rod and holding a piece of rubber or other desirablefloor engaging material 12. This tip is made removableso that it can bereadily replaced by another one when it' has become worn, or

The rubber or material 12 will prevent the floor from being injured. 7

A lever 13 is positioned horizontally withj in the casing 1 above thespring 5 and is abnormally in spaced horizontal relation thereto. Oneend of the lever is provided with a slot 14: to receive a pivot pin 15car ried by the casing, 'at a point adjacent with where the spring 5 isanchored to the easing. The other end of the leveris provided with afoot piece 16 which projects laterally through the L shaped slot 17 inthe casing. The lever 13 is also provided at a point intermediate itsends with a dependingfinger 18 bearing upon the spring 5 at a pointadjacent its free end.

In the operation of the device and when it is desired to check the doorin open position, the foot piece 16 is depressed and pushed horizontallyinto the horizontal portion of the L shaped slot 17 where it will remainunder tension of the spring 5 until disengaged by the foot. Thisactuation of the lever 14 will force the plunger rod downwardly untilthe tip thereof lockingly engages the floor, as clearly shown in Fig. 3.

It is to be further noted by this construction that the tip of theplunger rod will he held in locking engagement with the floor under ayielding spring tension whereby should the door be pushed violently, theplunger will yield from its engagement with the floor without anyliability of injuring the floor.

It is to be further understood that the device as described herein canbe used with equally as good effect upon a window frame and sash toserve as an anti-rattling device or a window check.

lVhile I have described the principle of operation together with thedevice I now consider to be the best embodiment thereof, I desire tohave it understood that such changes in construction and arrangement ofparts may be made when desired as within the scope of the appendedclaims.

Having thus fully described my invention what I claim as new is:

1. A device of the character described comprising a casing, a plungerslidable therein to bear against a floor or other object, a leaf springhaving one end anchored to the casing, said spring engaging said plungerto retract it from the object, and a manually operable member mounted inthe casing to contact with the spring and bend it to move said plungeragainst the object, said member and easing having means for holding saidmember when moved into contact with the sprin 2. A door check comprisinga casing, a spring positioned horizontally Within the casing and havingone end anchored to the casing, a plunger rod mounted through the bottomof the casing for vertical sliding movement and pivotally connected tothe free end of said spring, a lever positioned horizontally within thecasing above said spring and provided with means'for engagement withsaid spring, a foot piece carried by the lever projecting late 'allythrough the casing whereby the lever may be depressed to force saidplunger into engagement with the floor against the tension of said sprin3. A door check comprising a casing adapted to be attached to the lowerpart of the door, a supporting lug carried by the casing adjacent oneend thereof, a spring positioned horizontally within the casing oversaid supporting lug and having one end anchored to the casing, a plungerrod positioned through the bottom of the casing for vertical movementand having its inner end pivotally connected to the free end of saidspring, a lever positioned horizontally Within the casing above saidspring and provided with means for engagement with said spring, and afoot piece carried by the lever projecting through the casing wherebythe lever may be actuated to force the plunger into engagement with thefloor against the tension of said sprin 4. A door check comprising acasing' for attachment to the lower part of a door, a spring positionedhorizontally within the casing and having one end anchored to thecasing, a plunger rod mounted through the bottom of the casing forvertical movement and pivotally connected to the free end of saidspring, a lever mounted within the easing above said spring and havingone end provided with a slot, a pivot pin extending through said slot,means carried by the said lever engaging said spring, and a foot piececarried by the free end of the lever'and projecting through an L shapedslot inthe casing whereby said lever may be depressed and movedlongitudinally of the casing to lockingly engage the plunger rod withthe floor under spring tension.

5. A device of the character described comprising a casing, a plungerslidable therein to contact with a floor or other object, a leaf springanchored within the casing and engaging said plunger to retract it fromthe object, and a manuallyoperable lever mounted in the casing andhaving a portion to bear against the spring and bend it for moving theplunger against the object yieldingly, said lever and easing havingmeans for holding the lever when it is moved to bend the spring.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
